(Conventional technology)

BACKGROUND OF THE INVENTION [0002] Some mobile phones have been hingedly supported on a display module via a support to an operation module to be openable and attachable. In particular, when a large number of signal lines are required, in order to reduce the size of the device and to prevent fatigue disconnection of the signal lines due to the repeated operation of the display module, the operation module and the display module are provided through a flexible signal relay printed wiring film. Is electrically connected.

However, in the above-described mobile phone, the open display module cannot be rotated as if it is twisted, and the operation method is limited and it is inconvenient to use. For this reason, it is also conceivable to bundle and use a plurality of harnesses so that the display module can be twisted and operated. However, in the case of conveying a large amount of information, the number of harnesses increases, the torsion operation becomes difficult, and the apparatus cannot be miniaturized and is easily disconnected. For this reason, using a flexible printed wiring film is also examined, but when a torsion effect is applied to the said film, a complicated internal stress arises in a printed wiring film, and there exists a problem that a printed wiring peels easily and is disconnected.

SUMMARY OF THE INVENTION In view of the above problems, an object of the present invention is to provide a space-saving signal relay rotating motion structure which can be relayed without disconnecting a plurality of signal lines.

(Means to solve the task)

In order to achieve the above object, the signal relay rotational motion structure according to the present invention includes a fixed frame which is supported and fixed in a casing, and is rotatably inserted into an insertion through hole of the fixed frame and protrudes out of the casing. A rotational movement shaft, a rotational movement frame disposed outside the casing and fixed to the rotational movement integrally with a tip of the rotational movement shaft, and a tip of the rotational movement shaft being drawn out of the casing along the rotational movement axis, It is set as the structure which consists of a flexible printed wiring film wound around the winding snow piece located in a casing.

Therefore, according to the present invention, when the rotary frame is rotated, the rotary shaft rotates to rotate the printed wiring film clean. For this reason, even if the said rotation frame is rotated repeatedly, a complicated internal stress does not generate | occur | produce in a printed wiring film, and a printed wiring does not peel and disconnect.

In addition, by printing a large number of signal lines on a printed wiring film, a small device capable of transmitting a large capacity signal can be obtained.

The embodiment which concerns on this invention may be the structure which assembled the support body of the separate body provided with the winding tongue in one end in the casing of a rotating shaft.

According to this embodiment, since the printed wiring film is wound around the rotational motion axis and the support member which is separate, the degree of freedom of design is widened.

As one embodiment, at least one side of the fixing frame may be provided with a position limiting part for fixing to the winding of the printed wiring film so as not to be entangled.

According to this embodiment, since a printed film can be wound up smoothly or can be released, the durability of a printed wiring film can be improved further.

As another embodiment, it is sufficient to provide rotational motion limiting means for regulating the rotational motion of the fixed frame and the rotational motion frame.

According to this embodiment, breaking of the printed wiring film by the over-rotation movement of a rotation frame can be prevented.

As another embodiment, an elastic ring may be disposed between the fixed frame and the rotary motion frame in order to secure a so-called click feel.

According to this embodiment, an operation feeling improves and it becomes easy to use.

As embodiment of the printed wiring film which concerns on this invention, the extending part extended in the direction orthogonal to the axis center of the said winding part may be provided in at least one end of a straight winding part.

More specifically, at one end of the straight winding portion of the printed wiring film, a first extending portion extending in a direction orthogonal to the axis center of the winding portion is provided, while at the other end of the winding portion, the shaft core of the winding portion is provided. Orthogonal to and further, a second extending portion extending in the opposite direction to the first extending portion may be provided.

According to this embodiment, since the winding part and the extending | stretching part are arrange | positioned so that they may mutually orthogonally cross, the internal wiring does not generate complex internal stress, and it becomes difficult for a printed wiring to peel and disconnect.

In particular, the second extending portion of the printed wiring film may have a curved planar shape.

According to this embodiment, when winding a 2nd extending part, it does not overlap with each other and there exists an effect that it is easy to draw out.

EMBODIMENT OF THE INVENTION Embodiment which concerns on this invention is described according to attached drawing of FIGS.

This embodiment is a case where the signal relay rotational movement structure is applied to a mobile telephone, and the operation module 1 and the display module 2 are centered on two orthogonal shafts 9a and 9b through the support 10. It is attached to enable rotational movement.

As shown in FIG. 1, the operation module 1 protrudes a pair of ribs 3 and 4 attaching the display module 2 to both ends of an edge portion of one side thereof. In particular, a blind portion 7 having a U-shaped cross section is integrally formed near the inner side of the rib 4.

As shown in Fig. 1, the display module 2 is equipped with a liquid crystal panel 8 connected to a plurality of signal lines on one surface thereof. The display module 2 is screwed to the arm portions 44 and 45 of the rotational motion frame 42 constituting the support 10 described later.

As shown in FIG. 4, the support 10 includes an internal drive mechanism 40 that is fitted between the first casing 20 and the second casing 30.

As shown in FIG. 4, the first casing 20 has a concave portion 21 capable of accommodating the internal drive mechanism 40 on its upper surface, and ribs 22 and 23 are provided at both ends thereof. I am preparing. Moreover, while the swelling part 24 of the semicircular cross section is formed in the vicinity of the said rib 23, the recessed part 25 is formed between the said rib 23 and the said bulging part 24. As shown in FIG. .

As shown in FIG. 4, the second casing 30 has a planar shape capable of covering the first casing 20 on which the internal drive mechanism 40 is mounted. In particular, the second casing 30 has a symmetrical shape with the bulging portion 24 of the first casing 20, and integrally forms the bulging portion 31 at a position where the second casing 30 can be abutted.

As shown in FIG. 6 and FIG. 7, the internal drive mechanism 40 is constructed by assembling a flexible printed wiring film 70 to a drive unit 41 that performs a rotational motion operation.

That is, the drive unit 41 is the rotary motion cylinder 55 inserted into the through-hole 43 of the rotary motion frame 42 and caulked, and has the elastic ring 46, the fixed frame 47, and two pieces. The rotary motion stop rings 51 and 52 are integrated.

The rotary motion frame 42 has attachment arm portions 44 and 45 that are bent and formed at both ends thereof. The display module 2 is screwed to the arm parts 44 and 45.

The elastic ring 46 secures the click feeling necessary when the display unit 2 is twisted and rotated, and eliminates the rattling of the display module 2 relative to the operation module 1.

In the fixed frame 47, the positioning projections 48 and 49 are cut off from both sides thereof, respectively. The positioning members 59 and 62 described later are press-fitted into the positioning projections 48 and 49, respectively. Further, the engaging fixing hook 50 for stopping the rotational movement is erected near the insertion through hole 47a of the fixing frame 42.

The two rotary motion stop rings 51 and 52 respectively form a pair of position regulating ends 53 and 54 on the outer circumferential surface in order to restrict the rotary motion operation of the rotary motion frame 42 at a predetermined angle. . The rotation stop rings 51 and 52 are not necessarily two pieces, but may be one. Two pieces were made in order to make press work easy.

The rotary motion cylinder 55 is fixed by caulking after engaging the notch part 56 provided in the front-end | tip edge with the protrusion 43a formed in the insertion hole 43 of the rotary motion frame 42. As shown in FIG. For this reason, the rotary motion cylinder 55 rotates integrally with the rotary motion frame 42. Further, the flat surface 57 formed on the outer circumferential surface of the rotary motion cylinder 55 is coupled to the inner circumferential surface of the engaging hole of the elastic ring 46 and the two rotary motion stop rings 51 and 52. For this reason, when the said rotary frame 42 rotates, the elastic ring 46, the rotary stop rings 51, 52, and the rotary cylinder 57 rotate integrally.

In the position regulating member 59, the printed wiring film 70 is dropped or the printed wiring film 70 is not entangled when the rotary frame 42 is twisted about the rotary axis 9b. To regulate location. For this reason, as shown in FIG. 7, the said position regulating member 59 is integrally shape | molded by shifting the two engagement fixing | closing claws 60 and 61 about 90 degree | times.

The position regulating member 62 controls the position so that the printed wiring film 70 does not twist or become excessively twisted when the rotational movement frame 42 is rotated about the rotational axis 9a. It is. For this reason, as shown in Fig. 7, the position regulating member 62 has a semicircular cover 64 integrally formed on a concentric circle with a central axis 63 projecting laterally. .

As shown in FIG. 8A and FIG. 9, the printed wiring film 70 is perpendicular to the straight line of the long elongated winding portion 71 and the axis of the winding portion 71 and is further wound. It has the extending parts 72 and 73 extended from the both ends of 71 to the opposite side, respectively. Connection terminals 74 and 75 are printed on both of the front end portions of the extension portions 72 and 73. In particular, the extending portion 72 has a curved planar shape, and as shown in FIG.

The support member 76 supports and winds the said printed wiring film 70, as shown in FIG.

That is, the said support member 76 is the insertion part 77 which has a cross-sectional shape which can be inserted into the insertion hole 58 of the said rotary motion cylinder 55, and the positioning groove 78 provided in this insertion part 77. It consists of a fitting part 79 which fits and is integrated, and the winding tongue piece 80 extends laterally from the cross section of the said insertion part 77.

And after positioning the extension part 73 of the printed wiring film 70 in the positioning groove 78 of the said insertion part 77, the fitting part 79 is fitted and integrated. And the connection terminal 75 of the said printed wiring film 70 is inserted through the insertion hole 58 of the rotational motion cylinder 55, and let it pass. In addition, the insertion portion 77 of the support member 76 is inserted into the insertion hole 58 to be fitted. Then, the winding part 71 of the printed wiring film 70 is provided over the position regulating member 59, and the extending | stretching part 72 is wound around the support shaft 63 of the position regulating member 62. As shown in FIG.

The surface of the fitting portion 79 forming the support member 76 has a flat surface, and is inserted into and engaged with the insertion hole 58 of the rotary motion cylinder 55. For this reason, when the rotary motion frame 42 is rotated, the rotary motion cylinder 55 and the support member 76 are rotated integrally therewith, and the winding tongue piece 80 is wound around the printed wiring film 70. The mounting 71 is wound or released.

In this embodiment, even when the rotary motion frame 42 is rotated, it always works to wind up the printed wiring film 70 and does not act to be twisted. For this reason, there exists an advantage that a printed wiring does not peel and disconnect with a torsion effect.

Moreover, the said internal drive mechanism 40 which consists of the above-mentioned internal component is fitted to the recessed part 21 of the said 1st casing 20, as shown to FIG. 5A, 5B. While being determined, the edge portion 26 of the first casing 21 is fitted to the rotation frame 42 and the fixed frame 47.

Next, the usage method of the mobile telephone which concerns on this embodiment is demonstrated.

As shown in FIG. 1, the support 10 has support pins 5 and 6 inserted into the ribs 3 and 4 provided in the operation module 1 and the support holes 3a and 4a, respectively. Through this, it is attached to the rotational movement axis center (9a) to enable the rotational movement.

For this reason, as shown in FIG. 2, when the display module 2 screwed to the rotation frame 42 is rotated and opened about the shaft center 9a, the printed wiring film 70 located in the cover 64 is opened. ), The extending portion 72 is loosened. In addition, the extension part 72 opens in the cover 64 to absorb the displacement of the display module 2.

In addition, as shown in FIG. 3, the display module 2 is attached to the support 10 so as to be rotatable about the rotational axis 9b. For this reason, when the display module 2 is rotated about the rotational axis 9b, the rotational cylinder 55 coupled to it also rotates integrally. As a result, the elastic ring 46 fitted to the rotary motion cylinder 55, the rotary motion stop rings 51 and 52, and the support member 76 are integrally rotated. However, the fixed frame 47 does not rotate because it is fitted to the first casing 20 and the second casing 30.

By the rotational motion operation of the fixing frame 42, the support member 76 inserted into the rotational motion cylinder 55 rotates, and the winding tongue piece 80 is a winding portion 71 of the printed wiring film 70. ) Winding or unwinding Even if the supporting member 76 releases the printed wiring film 70, the printed wiring film 70 is positioned on the pair of fixing hooks 60 and 61 of the position regulating member 59, and the position is regulated. It is loosened about the support shaft 63 of the member 62. For this reason, the printed wiring film 70 does not get entangled apart from the position regulating member 59 and the position regulating member 62. As a result, as shown in FIG. 3C, the display module 2 can be folded to expose the liquid crystal panel 8 to the surface.

When the rotary frame 42 is rotated at a predetermined angle, the end portions 53 and 54 of the rotary stop rings 51 and 52 are caught by the hook 50 for positioning the fixed frame 47. . For this reason, the over-rotation movement of the said rotation frame 42 is prevented, and breaking of the printed wiring film 70 is avoided.

Moreover, you may not only wind the winding part 71 of the printed wiring film 70 to the winding tongue piece 80 of the support member 76, but also may wind it around multiple times. It is because it becomes difficult to produce a stress concentration in the said winding part 71 by winding up several times, and the disconnection of a printed wiring can be prevented more reliably. Moreover, when it winds around several times, the return force of the winding part 71 wound by the said winding tongue piece 80 increases, and there exists an advantage that a smooth release operation | movement can be implement | achieved.

In addition, the present invention is not limited to a mobile telephone, but may be applied to a digital video camera, a digital camera, a personal computer, a touch sensor, a car navigator, and the like in addition to a so-called portable input / output terminal apparatus such as an electronic notebook.

According to the present invention, when the rotary frame is rotated, the rotary axis rotates to rotate the printed wiring film cleanly. For this reason, even if the said rotation frame is rotated repeatedly, complicated internal stress does not generate | occur | produce in a printed wiring film, and a printed wiring does not peel and disconnect. In addition, by printing a large number of signal lines on a printed wiring film, there is an effect that a small device capable of transmitting a large capacity signal can be obtained.
